Atom, an RSS-derrived syndication format, 
has support for categorisation. See Tim's example
feed below. I think this should be mappable 
into SKOS fairly straightforwardly.

Feed items include elements such as:

<category scheme='http://www.tbray.org/ongoing/What/'
	term='Technology/Web' label='Technology/Web' />
<category scheme='http://www.tbray.org/ongoing/What/'
	term='Technology/Search' label='Technology/Search' />

4.2.2  The "atom:category" Element

   The "atom:category" element conveys information about a category
   associated with an entry or feed.

   atomCategory =
      element atom:category {
         atomCommonAttributes,
         attribute term { text },
         attribute scheme { atomUri }?,
         attribute label { text }?,
         empty
      }

4.2.2.1  The "term" Attribute

   The "term" attribute is a string that identifies the category to
   which the entry or feed belongs.  Category elements MUST have a
   "term" attribute.

4.2.2.2  The "scheme" Attribute

   The "scheme" attribute is an IRI that identifies a categorization
   scheme.  Category elements MAY have a "scheme" attribute.

4.2.2.3  The "label" attribute

   The "label" attribute provides a human-readable label for display in
   end-user applications.  The content of the "label" attribute is
   language-sensitive.  Category elements MAY have a "label" attribute.
]]

Perhaps the SKOS/Wordpress addon might be a good mechanism for
experimenting with mappings? I don't believe Atom says anything about 
the details of category schemes, nor what one would find upon 
dereferencing an Atom category URI.

In Tim's example, http://www.tbray.org/ongoing/What/ and 
http://www.tbray.org/ongoing/What/Technology/Search/ give HTML pages
whose primary topic is the category (and which list articles in that
category). Seems reasonable, though one might also imagine using such
URIs to find (by embedded or referenced RDF/XML) more information about 
categories and their inter-relationships.
